A disposer method allows the application to perform customized cleanup of an object returned by a
producer method or producer field.

A disposer method must be a non-abstract method of a managed bean class or session bean class. A disposer method may be
either static or non-static. If the bean is a session bean, the disposer method must be a business method of the EJB or a
static method of the bean class.

A bean may declare multiple disposer methods.

Each disposer method must have exactly one disposed parameter, of the same type as the corresponding producer method or
producer field return type. When searching for disposer methods for a producer method or producer field, the container
considers the type and qualifiers of the disposed parameter. If a disposed parameter resolves to a producer method or
producer field declared by the same bean class, the container must call this method when destroying any instance returned by
that producer method or producer field.

In addition to the disposed parameter, a disposer method may declare additional parameters, which may also specify
qualifiers. These additional parameters are injection points.

A disposer method may resolve to multiple producer methods or producer fields declared by the bean class, in which case the
container must call it when destroying any instance returned by any of these producer methods or producer fields.
